Question

2 Resuelve las siguientes operaciones combinadas en tu cuaderno:
a.
$- 5 + 4 \times 3 =$
b
$6 - 2 \times 5 =$
c.
$32 - 40 \times 5 + 128 =$
d.
$(8 - 3) \times 4 - 1 =$
e.
$( 8 - 3) \times 4 - 1 =$
e.
$( - 13 + 6) \times ( - 3) + 4( - 1) =$
​

Answer 1

a. -5+4*3 = -5 + 12 = 7

b. 6-2*5= 6-10= -4

c. 32-40*5+128= 32 - 200 +128 = - 40

d. (8-3) * 4 -1 = 5*4-1 = 20 - 1 = 19

e. (8-3) * 4 -1 = 5*4-1 = 20-1 = 19

e. (-13+6) * (-3) + 4 (-1) = (-7) * (-3) -4 = 21-4 = 17
